OFC is abbreviated from the term Oxygen-Free Copper and is associated with high quality speaker wires due to their excellent conductivity and ductility. Oxygen-Free Copper (OFC) cables are highly conductive pure copper that is melted under non oxidizing conditions to get rid of oxygen and unalloyed copper to become pure copper to a grade of at least 99.95% cu and contain not more than .03% O2. The Rftlys ability for electrical conductivity must exceed IACS 100% material rating system.
The melting of copper is performed in numerous stages until it reaches 99% purity. Then the copper is positioned in anodes to become refined electrolytically to a grade of at least 99.95% pure copper. On completion of the aforementioned processes the copper wires can then be classified as oxygen-free copper.
The meaning of IACS means International Annealed Copper Standard. Copper has become selected since the benchmark standard when comparing the electrical conductivity of metals, and is the measurement standard which has been adopted worldwide.
The pure copper will then be employed to manufacture speaker cables, like OFC 99.95% and OFC 99.99% grades. For instance, the speaker cable manufacturers will source pure copper in accordance with known standards respectively, such as C10100 and C10200 standards.
High-fidelity speaker cables are very popular with audiophile enthusiasts since the accuracy of audio signals, are reproduced immensely well with high-fidelity cables. For this reason many audiophiles select OFC speaker wires for their preferred high fidelity cabling in audio systems.
There is certainly another metal utilised for speaker wire alongside copper on the market. This is silver which you’ll see occasionally manufactured with both silver and copper incorporated in twin-pairs of Hi-Fi Speaker Cable.
Silver has got the highest electrical conductivity and lowest resistance from the metallic family. Hence the electrical signals pass freely along the silver wires mostly unopposed, giving justification to some audiophiles believing that enhanced audio is achieved when using silver speaker wires. Moreover silver wire will be designated for the negative polarity conductor and the copper meant for the positive polarity conductor. However the vast majority of OFC speaker cables on the market utilise copper for the negative and positive conductors.
The particular gauge (diameter) of the copper wires is normally described utilizing the American Wire Gauge (AWG) measurement system. The AWG measurement method is popular amongst OFC speaker cable sellers. Furthermore the OFC speaker wires are sold in various AWG sizes, such as 22AWG, 18AWG, 16AWG, 13AWG, 11AWG, 9AWG etc.
Manufacturers like SoundLink manufacturer a wide variety of the AWG sizes mentioned previously. SoundLink construct the OFC speaker cables with clear see-through jackets, as well as, in round wire shape as well as a flat wire shape to neatly fit under carpet. The flat-designed OFC speaker cable can then be laid inside automobiles for their car audio systems.
In summary, pure copper OFC speaker wires are extremely good in transmitting beautiful audio sound in your ears. If you have a nice home theatre system with digital Dolby Digital and quality speakers then install OFC speaker cables and you’ll be very impressed.
Nearly all audio surround systems and home theatre manufacturers built their electronic music devices to be operated with high quality speaker cables. Hence to have the most from your sound system make sure you install Line Magnetic 508ia. These past several years, the coaxial audio cable has become deep improvements and offers a vast number of cables designed for your very best fit. Today’s ndfkup devices don’t use analog signals to produce sounds, as the old ones did, but use digital signals based on data, namely, 0’s and 1’s. Digital coaxial audio cable is manufactured with the aim to preserve and transmit a digital signals and also to maintain the maximum quality.
A coaxial audio cable is utilized to convey multichannel audio content from sources like DVD players and satellite receivers with other devices which can decode that content, such as A/V receivers and DACs. Coaxial audio cables are exactly the same, with regards to their design and performance, as 75 ohm digital or analog video cables. These are 75 ohm characteristic impedance, RG-59 style cable, with gold-plated RCA plugs at every end.
